ing the reinforcing.:l bars in vparallel relationship in the forms `and at 'the proper median bend thus formed and forni supports for said device, spaced openings along said bend, said openings extending the same 'distance from the said median line on either side thereof whereby .a series 'of spaced notches is' rovided along the .bend at' equal distances rom the 'plane of. support, the

` length and width lof the openings being so proportioned that the notches thus formed 'are slightly Wider than a reinforcing bar and of substantially the same depth, and tongues projecting into said openings, said tongues being positioned at the median line of the strip and extending transversely thereto in a plane through the apex .of the `bend and parallel to the plane lof the ex- '.ing

tremities of the'margins of the strip, said tongues being adapted to' overlie re1nforcbars positioned ,in said notches at right anglesv to the longitudinal axis of the del`vic-e, the width lof the prongs bein such that when the spacing members an reinforcing bars yare in such relative position 'that the prongs extend- `in a direction parT allelfwith that ofthe reinforcing bars the latter may be slipped into'qor out of the notches Without distortingthe prongs.

2. In a -metal reinforce or concrete structures,l the combination of parallel reinforcing bars with 'transversely arranged supporting and spacing members, said spacing members being provided with notches along their upper edges slightly Wider than the reinforcing bars 'and of substantially the same depth, and prongs projecting from thevupper edges of the spacing members along their median line at nearly right `angles thereto ,and parallel With-the plane of the reinforcing bars, the Width ofthe prongs bein membersvan relative position that the prongs extend in a direction parallel with that of the reinf,

forcing bars the latter may be slipped into such that when "the .spacing reinforcing bars are in such the notches Without distorting the prong;

whereupon the spacing members may swung around until they cross the re1nforc- `ing bars atright angles and the prongs will then overlie'the bars.
